What are the main symptoms of Gerstmann's syndrome?

Gerstmann's syndrome is characterized by a specific set of cognitive and perceptual disturbances that arise from damage, typically in the left parietal lobe of the brain. The hallmark symptoms of this syndrome include finger agnosia, which is the inability to recognize or identify one's own fingers or the fingers of others, and right-left confusion, where an individual has difficulty distinguishing between the right and left sides of their own body or the environment.

The syndrome often also involves agraphia (difficulty in writing) and acalculia (difficulty in performing mathematical calculations). The presence of finger agnosia and right-left confusion directly relates to the spatial and associative functions of the parietal lobe, indicating the critical role this brain region plays in integrating sensory information and aiding in body awareness and coordination.

The other options presented refer to symptoms associated with different neurological or psychological conditions. For example, visual agnosia and auditory processing deficits are typically linked to other types of brain injuries or disorders, memory loss and confabulation are more characteristic of amnesic syndromes, and pseudodepression and poor hygiene relate to different psychiatric or neurologic conditions, such as certain dementias or mood disorders. Therefore, the distinct combination of finger agnosia
